这个题本身有问题。if从句显然表示的是与过去事实相反的假设,应该是 If I had been on the spot that day, 主句也是表示的是推测出来的过去结果,所以用would have been able. 在一些文学作品中,有时if从句表示与过去事实相反,be也用were的形式,由于were用作第一和第三人称单数后,已经清楚表明是虚拟语气,所以就用we...

among介词短语在此的意思是除了...之外。前面句子表述的是主要negative effects,其他次要的就不细说了。重点在前面说的内容,所以次要的内容就不用谓语表示,而降格为状语。如果改用and has many other, 给人的印象是你还在强调其他方面。所以,句子的侧重点就不同了。

home在此为副词,和to介词短语都可以作方向状语,也可以作目的地状语。当谓语为一般过去时的时候,通常理解动词结束了,home和to介词短语都分析为目的地的地点状语。home表示大的地点,to介词短语表示具体的小的地点,即他祖父所在的那个位置。二个副词性结构之间互相没有修饰关系,而是二者结合共同描述hurried这个动作最...

1 while引导时间从句时,从句谓语通常是不能用非延续动词的。所以这里应该是作者的疏忽,改为while the news was broadcast. 这样主句和从句都是延续性动词,都用一般体。2 throw是非延续动词,用进行体表示撒的动作是重复发生的。fly为延续性动词,用一般体就可以表示很多的鸟飞下来。这样不断撒的动作和不断有鸟飞下来吃...

很显然,最后二个句子中的pass是不及物动词,意为go (from sth)to sth, 只不过加了一个副词on表示继续的意思。这并不是短语动词 pass sth on, pass on sth 。你把二者混淆了。

不需要。但这个句子需要改进,因为it指代不明,改为 it is still arduous to deal with them. 让不定式短语作真正主语,it为形式主语。

你理解错误。before和after作为连词引导从句时,从句是不允许省略主语和be的。before being done是介词+动名词结构。before done是错误。
